DETAILED DESCRIPTION

To enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. It is apparent that the described embodiments are merely some, rather than all of the embodiments of the present application. On the basis of the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts should fall within the protection scope of the present application.

One embodiment can provide a method for displaying an identification code of an application. The method can be applied to a terminal device, such as a mobile phone, a tablet computer, or a computing device. By means of the method provided by the disclosed embodiments, when an identification code needs to be displayed, it is unnecessary to open a target application or to search for the identification code in a menu of the target application. Only an icon of the target application needs to be displayed. Hence, it is convenient for a user to display the identification code of the target application, and the required operation is simple and less time-consuming.

FIG. 1 presents a flowchart of a method for displaying an identification code of an application, according to one embodiment. The method shown in FIG. 1 includes at least the following operations:

Operation S102: acquire an identification code in a target application in a system user interface (UI), where the identification code is generated by the target application according to user information in the target application.

The target application refers to a target application in a system UI of a terminal device. The target application may be any application installed in the terminal device, such as a payment application, a user-authentication application, an access-control application, or a membership-card application.

The “user information in the target application” in this embodiment refers to user information left by a user in the target application when the user is using the target application in the terminal device, such as personal information or account information left by the user in the target application when the user logs in to the target application. Accordingly, the identification code generated by the target application according to the user information in the target application can be an identification code generated according to the user information of the user. For example, a target application B is installed on a mobile phone of a user A, and user A uses the mobile phone to open target application B and logs in, then the target application B on the mobile phone acquires corresponding user login information, such as personal information of user A. At this time, target application B may generate, according to the personal information of user A, a corresponding identification code, such as an identification code corresponding to the personal information of user A or a payment identification code for making payment by the user A.

The aforementioned target application carries the user information. In order to protect the user's privacy and to facilitate the use of the target application by the user, the target application generally generates an identification code according to the user information, such that the user can conveniently display the identification code to other users when using the mobile device.

The identification code can be an identification code pattern. The identification code can be a pure 2D code or bar code, or can be a combined pattern of a plurality of individual patterns. In one embodiment, the identification code can includes any one of the following:

a 2D code, a bar code, a pattern formed by at least a 2D code and a logo pattern of the target application, a pattern formed by at least a bar code and the logo pattern of the target application, and an arrangement trajectory of icons of a plurality of predetermined applications displayed in the system UI.

The logo pattern of the target application can be an icon of the target application or a name of the target application.

In one embodiment, the identification code being a pattern formed by at least a 2D code and the logo pattern of the target application can include: the identification code being a pattern formed by a 2D code and the logo pattern of the target application, or the identification code being a pattern formed by a 2D code, the logo pattern of the target application, and other content. Similarly, the identification code being a pattern formed by at least a bar code and the logo pattern of the target application can include: the identification code being a pattern formed by a bar code and the logo pattern of the target application, or the identification code being a pattern formed by a bar code, the logo pattern of the target application, and other content.

To facilitate the understanding of the identification code being a pattern formed by at least a 2D code and the logo pattern of the target application or a pattern formed by at least a bar code and the logo pattern of the target application, following examples are provided.

In one example, the target application can be Alipay™, and the logo pattern of the target application can include a Chinese character “

.” Specifically, the identification code can be a pattern formed by a 2D code and the character “

,” or the identification code can be a pattern formed by a bar code and the character “

.” Within the identification code, the location of the character “

” and the 2D code or the bar code may be arbitrarily configured. FIG. 2(a), FIG. 2(b), FIG. 2(c), and FIG. 2(d) show several possible forms of the identification code.

In FIG. 2(a), the identification code can be formed by a bar code and the character “

;” the bar code occupies the lower half region of the entire identification code; the character “

” occupies the upper half region of the entire identification code. In FIG. 2(b), the identification code can be formed by a 2D code and the character “

;” the 2D code occupies the lower half region of the entire identification code; and the character “

” occupies the upper half region of the entire identification code. In FIG. 2(c), the identification code is formed by a 2D code and the character “

;” the 2D code is located in the bottom layer of the identification code and occupies the entire region of the identification code; and the character “

” floats on the top layer of the 2D code. In the identification code shown in FIG. 2(d), the identification code is formed by a 2D1 code and the character “

;” the identification code is located in the bottom layer of the identification code; the character “

” is disposed in the lower-right corner region of the 2D code and partially overlaps the 2D code.

Certainly, the aforementioned FIG. 2(a), FIG. 2(b), FIG. 2(c), and FIG. 2(d) only show several possible forms of the identification code being a pattern formed by a 2D code (or a bar code) and the character “

.” However, the pattern formed by a 2D code (or a bar code) and the character “

” is not limited to these examples, and may also be in other forms, which will not be enumerated in the present application.

For example, in another embodiment, to facilitate the user in identifying the target application, the identification code may be a pattern formed by a 2D code, the character “

” of Alipay, and the word “Alipay.” A possible form is shown in FIG. 2(e).

In the identification code shown in FIG. 2(e), the character “

” is located in the middle region of the 2D code, and the word “Alipay” is located in the bottom region of the 2D code.

Furthermore, in one embodiment, the identification code can be an arrangement trajectory of icons of a plurality of predetermined applications located in the system UI.

For example, in one specific implementation, a plurality of applications located in the same UI of the system can be selected, and a trajectory pattern obtained by arranging and combining icons of the selected applications can be used as an identification code. As shown in FIG. 2(f), icons of selected applications may be arranged into a “Z” shape to serve as an identification code.

In one embodiment, acquiring an identification code in a target application in a system UI in the aforementioned operation S102 specifically includes:

acquiring the identification code in the target application at a predetermined time interval;

and/or acquiring the identification code in the target application when a user launches the target application.

In one embodiment, if the identification code remains unchanged after the identification code is displayed in an icon-display region of the target application, then the identification code may be leaked, leading to leakage of user information, causing security risks. Therefore, in order to ensure the security of user information, the identification code displayed in the icon-display region of the target application may be updated periodically.

In one embodiment, acquiring an identification code in a target application in a system UI in the aforementioned operation S102 includes at least the following three cases:

Case 1: acquiring the identification code in the target application at a predetermined time interval.

The predetermined time interval may be any value, such as 2 seconds, 10 seconds, 1 minute, or 10 minutes. The specific value of the predetermined time interval may be set according to the actual implementation. The specific value of the predetermined time interval is not limited in embodiments of the present application.

In one specific implementation, the identification code in the target application is updated at a certain time interval, for example, updated every few minutes. In one embodiment, a current identification code in the target application can be acquired from the target application at a predetermined time interval. Data corresponding to the identification code may be acquired.

In another implementation, the identification code in the target application may further be acquired directly from a server at a predetermined time interval. Certainly, data corresponding to the identification code may be acquired from the server.

In one embodiment, the identification code in the target application is acquired at a predetermined time interval, such that the identification code displayed in the icon-display region of the target application can be updated, thereby improving the security of user information.

Case 2: acquiring the identification code in the target application when a user launches the target application.

In this case, when the user launches the target application, update of the identification code displayed in the icon-display region of the target application is triggered. That is, when the user launches the target application, a current identification code of the target application is acquired from the target application.

Case 3: when the user launches the target application, acquisition of the identification code in the target application at a predetermined time interval by the terminal device is triggered.

In this case, when the user launches the target application, acquisition of the identification code in the target application at a predetermined time interval within a period of time may be triggered.

Operation S104: display the identification code in an icon-display region of the target application in the system UI.

After the identification code in the target application is acquired, the identification code is displayed in the icon-display region of the target application. This way, when the user needs to use the identification code for payment, authentication, or the like, the user can directly display an icon of the target application in the system UI to other users to facilitate the user's operation.

In the aforementioned operation S104, displaying the identification code in an icon-display region of the target application in the system UI in fact is using the identification code in place of the original icon of the target application.

For example, the aforementioned target application is Alipay, and a schematic diagram illustrating the effect of displaying an identification code of Alipay in an icon-display region of Alipay is shown in FIG. 3

Furthermore, in some scenarios, for the target application, a same user may have a plurality of accounts, and different accounts can correspond to different user information. When the user logs in to another account of the target application in the same terminal device, if the icon-display region of the target application still displays an identification code corresponding to an original account, then the identification code displayed to other users is a wrong identification code. Thus, when user information in the target application changes, the identification code displayed in the icon-display region of the target application also needs to be updated accordingly. Therefore, the method for displaying an identification code of an application provided by an embodiment of the present application can further include:

when the user information in the target application changes, updating the identification code in the target application according to the changed user information, and displaying the updated identification code in the icon-display region of the target application in the system UI.

In one embodiment, changing of the user information can include: logging in to a different account in the target application, the user modifying information in the target application, or the like.

In one embodiment, when it is detected that the user information of the target application changes, the identification code in the target application is updated according to the changed information; moreover, after the identification code in the target application is updated, the identification code of the information in the target application is acquired, and the identification code currently displayed in the icon-display region of the target application is updated to the newly acquired identification code.

Furthermore, in one embodiment, because the identification code is displayed in the icon-display region of the target application, and the icon-display region of the target application has a small area, the displayed identification code appear to be small; moreover, in some cases, the identification code may further include other patterns, causing only part of it to be the effective identification code when in use. Thus, when the identification code is used, a scanning device may be unable to scan the identification code, resulting in an identification failure or identification error. Therefore, in order to improve the success rate and accuracy of identification, the method provided by embodiments of the present application further includes the following steps (1) and (2):

Step (1): receiving an operation performed by the user on the terminal device; and

Step (2): performing an enlarging operation on a predetermined region in the identification code in response to the above operation.

The operation in step (1) may be any gesture operation such as a press operation, a long-press operation, or a zoom operation performed on a screen of the terminal device; or the operation can be a voice input operation or the like.

The predetermined region in step (2) may be the entire region of the identification code, or may be a partial region in the identification code, such as a 2D code or bar code region in the identification code.

In one specific implementation, when the user displays the identification code to another user, before the other user uses a scanning device to scan the identification code, the user can perform a gesture operation on the terminal device. After the terminal device receives the gesture operation performed by the user, the predetermined region of the identification code is enlarged, thus facilitating the scanning device in scanning the enlarged identification code, thereby improving the success rate and accuracy of identification.

Furthermore, in one embodiment, because the user can display the identification code without the need to launch the target application, in order to allow the user to conveniently learn the identification result of the identification code, the method for displaying an identification code of an application provided in some embodiments of the present application further includes:

receiving first prompt information pushed by a server, indicating that the identification code is successfully identified; and displaying the first prompt information in the system UI;

or

receiving second prompt information pushed by the server, indicating that the identification code has expired; and displaying the second prompt information in the system UI.

In one embodiment, if the identification code is successfully identified, then the server pushes to the terminal device first prompt information indicating successful identification, and after the terminal device receives the first prompt information pushed by the server, it displays the first prompt information in the current system UI; if it is detected that the identification code has expired, then the server pushes to the terminal device second prompt information indicating that the identification code has expired, and after the terminal device receives the second prompt information pushed by the server, it displays the second prompt information in the current system UI.

In one specific implementation, if the aforementioned target application is Alipay and the aforementioned identification code is a 2D code, then a schematic diagram illustrating a display interface of the aforementioned first prompt information is shown in FIG. 4(a), and a schematic diagram illustrating a display interface of the aforementioned second prompt information is shown in FIG. 4(b).

In one embodiment, identification-related information of the identification code is pushed to the terminal device using a method of pushing a system message, thus facilitating the user in learning the current identification situation at any time, thereby enhancing interactions between the terminal device and the server and improving user experience.

The method for displaying an identification code of an application provided by one embodiment displays an identification code in a target application in a system UI in an icon-display region of the target application, such that when the identification code is needed for display, it is neither necessary to launch the target application nor to search for the identification code in a menu of the target application, only an icon of the target application needs to be displayed. Thus, it is convenient for a user to display the identification code of the target application, and such an operation is simple, convenient, and less time-consuming.

Based on the method shown in FIGS. 1-4, one embodiment further provides a method for displaying an identification code of an application.

In the case shown in FIG. 6(b), the identification code is displayed over the entire region of the wallpaper. That is, the identification code is used as the wallpaper of the system UI.

Furthermore, in one embodiment, when the identification code is displayed in the specified region in the system UI, in order to prevent the occurrence of an identification failure or identification error due to a small identification code, after the identification code is displayed to other users, before the other user uses a scanning device to scan the identification code, the method provided by one embodiment may further include the following steps:

receiving an operation performed by the user on the terminal device; and performing an enlarging operation on a predetermined region in the identification code in response to the operation.

The operation in the aforementioned step may be any gesture operation, such as a press operation, a long-press operation, or a zoom operation performed on a screen of the terminal device; or the operation may further be a voice input operation or the like.

The predetermined region in the aforementioned step may be the entire region of the identification code, or may be a 2D code or bar code region in the identification code.

In one specific implementation, when the user displays the identification code to other users, before the other user uses a scanning device to scan the identification code, a gesture operation may be performed on the terminal device, and after the terminal device receives the gesture operation performed by the user, the predetermined region of the identification code is enlarged, thus facilitating the scanning device in scanning the enlarged identification code, thereby improving the success rate and accuracy of identification.

Furthermore, in one embodiment, because the user can display the identification code without the need to launch the target application, in order to allow the user to conveniently learn an identification result of the identification code, the method for displaying an identification code of an application provided by one embodiment further includes:

receiving first prompt information pushed by a server indicating that the identification code is successfully identified; and displaying the first prompt information in the system UI;

or

receiving second prompt information pushed by the server indicating that the identification code has expired; and displaying the second prompt information in the system UI.

In one embodiment, if the identification code is successfully identified, then the server pushes to the terminal device first prompt information indicating successful identification, and after the terminal device receives the first prompt information pushed by the server, the first prompt information is displayed in the current system UI; if it is detected that the identification code has expired, then the server pushes to the terminal device second prompt information indicating that the identification code has expired, and after the terminal device receives the second prompt information pushed by the server, the second prompt information is displayed in the current system UI.

Furthermore, in some scenarios, for the target application, a same user may have multiple accounts, and different accounts correspond to different user information. If the user logs in to another account of the target application in the same terminal device, and the icon-display region of the target application still displays an identification code corresponding to an original account, then the identification code displayed to other users is a wrong identification code. Thus, when the user information in the target application changes, the identification code displayed in the icon-display region of the target application also needs to be updated accordingly. Therefore, the method for displaying an identification code of an application provided by one embodiment further includes:

when the user information in the target application changes, updating the identification code in the target application according to the changed user information, and displaying the updated identification code in the specified region in the system UI.

In one embodiment, changing in user information may include: logging in to a different account in the target application, the user modifying information in the target application, or the like.

In one embodiment, when it is detected that the user information of the target application changes, the identification code in the target application is updated according to the changed information; moreover, after the identification code in the target application is updated, the identification code of the user information in the target application is acquired, and the identification code currently displayed in the specified region in the system UI is updated to the newly acquired identification code.

The method for displaying an identification code of an application provided in one embodiment displays an identification code of a target application in a specified region in a system UI, such that when the identification code needs to be displayed, it is neither necessary to open the target application nor to search for the identification code in a menu of the target application, and only a page currently displayed by a terminal device needs to be switched to the system UI displaying the identification code. Thus, the operation is simple and convenient and less time-consuming.

Based on the method shown in FIG. 1 to FIG. 4, one embodiment further provides a method for displaying an identification code of an application. FIG. 7 presents a flowchart of a third method for displaying an identification code of an application, according to one embodiment. The description herein focuses on differences between the method shown in FIG. 7 and the method shown in FIGS. 1 to 4. Reference may be made to the description of the method for displaying an identification code of an application provided in the aforementioned embodiment for similarities, which will not be described herein again. The method shown in FIG. 7 includes at least the following operations:

Operation S302: display, in an icon-display region of a target application of a system UI, an identification code in the target application.

The identification code is generated by the target application according to user information in the target application.

The target application refers to a target application in a system UI of a terminal device. The target application may be any application installed in the terminal device, for example, a payment application, a user authentication application, an access-control application, or a membership card application.

The aforementioned target application carries the user information. In order to protect the user's privacy and facilitate the user in using the target application, the target application generally generates an identification code according to the user information, such that the user can conveniently display the identification code to other users during use.

The identification code may be an identification code pattern. The identification code may be a pure 2D code or bar code, or may be a combined pattern of a plurality of patterns. Thus, in one embodiment, the identification code includes any one of the following:

a 2D code, a bar code, a pattern formed by at least a 2D code and a logo pattern of the target application, a pattern formed by at least a bar code and the logo pattern of the target application, and an arrangement trajectory of icons of multiple predetermined applications located in the system UI.

The logo pattern of the target application may be an icon of the target application or a name of the target application.

In one embodiment, the identification code being a pattern formed by at least a 2D code and the logo pattern of the target application includes: the identification code being a pattern formed by a 2D code and the logo pattern of the target application, or the identification code being a pattern formed by a 2D code, the logo pattern of the target application, and other content; similarly, the identification code being a pattern formed by at least a bar code and the logo pattern of the target application includes: the identification code being a pattern formed by a bar code and the logo pattern of the target application, or the identification code being a pattern formed by a bar code, the logo pattern of the target application, and other content.

Displaying the identification code in an icon-display region of the target application in the system UI in the aforementioned operation S302 actually means using the identification code to replace the original icon of the target application.

Furthermore, before the aforementioned operation S302 is performed, the method provided in one embodiment further includes the following operation:

acquiring the identification code in the target application in the system UI.

Acquiring the identification code in the target application in the system UI specifically includes:

acquiring the identification code in the target application at a predetermined time interval;

and/or acquiring the identification code in the target application when a user launches the target application.

In one embodiment, if the identification code remains unchanged after the identification code is displayed in an icon-display region of the target application, then the identification code may be leaked, thus leading to leakage of user information, causing security risks. Therefore, in order to ensure the security of user information, the identification code displayed in the icon-display region of the target application may be updated periodically.

Specifically, acquiring the identification code in the target application in the system UI includes at least the following three cases:

Case 1: acquiring the identification code in the target application at a predetermined time interval.

The predetermined time interval may be any value, such as 2 seconds, 10 seconds, 1 minute, or 10 minutes. The specific value of the predetermined time interval may be set according to the actual implementation. The specific value of the predetermined time interval is not limited by embodiments of the present application.

In one specific implementation, the identification code in the target application is updated at a certain time interval, for example, updated every few minutes. In one embodiment, a current identification code of the target application may be acquired from the target application at a predetermined time interval. Data corresponding to the identification code may be acquired.

In another implementation, the identification code in the target application may further be acquired directly from a server at a predetermined time interval. Certainly, data corresponding to the identification code may be acquired from the server.

In one embodiment, the identification code in the target application is acquired at a predetermined time interval, such that the identification code displayed in the icon-display region of the target application can be updated, thereby improving the security of user information.

Case 2: acquiring the identification code in the target application when a user launches the target application.

In this case, when the user launches the target application, update to the identification code displayed in the icon-display region of the target application is triggered. That is, when the user launches the target application, a current identification code of the target application is acquired from the target application.

Case 3: triggering acquisition of the identification code in the target application at a predetermined time interval by the terminal device when the user launches the target application.

In this case, when the user launches the target application, acquisition of the identification code in the target application at a predetermined time interval within a period of time may be triggered.

Furthermore, in one embodiment, because the identification code is displayed in the icon-display region of the target application and the icon-display region of the target application has a small area, causing the displayed identification code to be small; moreover, in some cases, the identification code further includes other patterns, causing only part of it to be the effective identification code during use. As a result, when the identification code is used, a scanning device may be unable to scan the identification code, resulting in an identification failure or identification error. Therefore, in order to improve the success rate and accuracy of identification, the method provided in one embodiment further includes the following steps:

receiving an operation performed by the user on the terminal device; and performing an enlarging operation on a predetermined region in the identification code in response to the user operation.

The operation in the aforementioned step may be any gesture operation, such as a press operation, a long-press operation, or a zoom operation performed on a screen of the terminal device; or the operation may further be a voice input operation or the like.

The predetermined region in the aforementioned step may be the entire region of the identification code, or may be a partial region in the identification code, for example, a region corresponding to a 2D code or a bar code.

In one specific implementation, when the user displays the identification code to other users, before the other user uses a scanning device to scan the identification code, the user can perform a gesture operation on the terminal device, and after the terminal device receives the gesture operation, the predetermined region of the identification code is enlarged, thus facilitating the scanning device in scanning the enlarged identification code, thereby improving the success rate and accuracy of identification.

Furthermore, in one embodiment, because the user can display the identification code without the need to launch the target application, in order to allow the user to conveniently learn an identification result of the identification code, the method for displaying an identification code of an application provided by one embodiment further includes:

receiving first prompt information pushed by a server indicating that the identification code is successfully identified; and displaying the first prompt information in the system UI;

or

receiving second prompt information pushed by the server indicating that the identification code has expired; and displaying the second prompt information in the system UI.

In one embodiment, if the identification code is successfully identified, then the server pushes to the terminal device first prompt information indicating successful identification, and after the terminal device receives the first prompt information pushed by the server, it displays the first prompt information in the current system UI; if it is detected that the identification code has expired, then the server pushes to the terminal device second prompt information indicating that the identification code has expired, and after the terminal device receives the second prompt information pushed by the server, it displays the second prompt information in the current system UI.

Furthermore, in some scenarios, for the target application, a same user may have multiple accounts, and different accounts correspond to different user information. If the user logs in to another account of the target application in the same terminal device, and the icon-display region of the target application still displays an identification code corresponding to an original account, then the identification code displayed to other users is a wrong identification code. Thus, when the user information in the target application changes, the identification code displayed in the icon-display region of the target application also needs to be updated accordingly. Therefore, the method for displaying an identification code of an application provided by one embodiment further includes:

when the user information in the target application changes, updating the identification code in the target application according to the changed user information, and displaying the updated identification code in the icon-display region of the target application in the system UI.

In one embodiment, changing the user information may include: logging in to a different account in the target application, the user modifying information in the target application, or the like.

In one embodiment, when it is detected that the user information of the target application changes, the identification code in the target application is updated according to the changed information; moreover, after the identification code in the target application is updated, the identification code of the information in the target application is acquired, and the identification code currently displayed in the icon-display region of the target application is updated to the newly acquired identification code.

The method for displaying an identification code of an application provided by one embodiment displays an identification code in a target application in a system UI in an icon-display region of the target application, such that when the identification code needs to be displayed, it is neither necessary to open the target application nor to search for the identification code in a menu of the target application, and only an icon of the target application needs to be displayed. Thus, it is convenient for a user to display the identification code of the target application, and the operation is simple, convenient and less time-consuming.

Based on the method shown in FIG. 1 to FIG. 6, one embodiment further provides a method for displaying an identification code of an application. FIG. 8 presents a flowchart of a fourth method for displaying an identification code of an application, according to one embodiment.

acquiring the identification code in the target application at a predetermined time interval;

and/or acquiring the identification code in the target application when a user launches the target application.

In one embodiment, if the identification code remains unchanged after the identification code is displayed in an icon-display region of the target application, then the identification code may be leaked, thus leading to user information leakage, causing security risks. Therefore, in order to ensure the security of user information, the identification code displayed in the icon-display region of the target application may be updated periodically.

In one embodiment, the acquiring an identification code in a target application in a system UI includes at least the following three cases:

Case 1: acquiring the identification code in the target application at a predetermined time interval.

The predetermined time interval may be any value, such as 2 seconds, 10 seconds, 1 minute, or 10 minutes. The specific value of the predetermined time interval may be set according to the actual implementation. The specific value of the predetermined time interval is not limited by embodiments of the present application.

In one specific implementation, the identification code in the target application is updated at a certain time interval, for example, updated every few minutes. In one embodiment, a current identification code of the target application may be acquired from the target application at a predetermined time interval. Data corresponding to the identification code may be acquired.

In another implementation, the identification code in the target application may further be acquired directly from a server at a predetermined time interval. Certainly, data corresponding to the identification code may be acquired from the server.

That is, when the user launches the target application, a current identification code of the target application is acquired from the target application.

Case 3: triggering acquisition of the identification code in the target application at a predetermined time interval by the terminal device when the user launches the target application.

In this case, when the user launches the target application, acquisition of the identification code in the target application at a predetermined time interval within a period of time may be triggered.

Furthermore, in one embodiment, when the identification code is displayed in the specified region in the system UI, in order to prevent the occurrence of an identification failure or identification error caused by a small identification code, after the identification code is displayed to another user and before the other user uses a scanning device to scan the identification code, the method provided in one embodiment may further include the following steps:

In the 1990s, whether a technical improvement is a hardware improvement (for example, an improvement on a circuit structure such as a diode, a transistor, or a switch) or a software improvement (an improvement on a method procedure) can be differentiated clearly. However, following the development of technologies, currently many improvements on method procedures can be regarded as direct improvements on hardware circuit structures. Almost all designers can program an improved method procedure into a hardware circuit to obtain a corresponding hardware circuit structure. Therefore, it cannot be said that an improvement on a method procedure cannot be implemented by a hardware entity module. For example, a programmable logic device (PLD) (e.g., a field programmable gate array (FPGA)) is such an integrated circuit, whose logic function is determined by device programming of a user. The designers may program by themselves to “integrate” a digital system with a PLD, and there is no need to ask a chip manufacturer to design and manufacture an application specific integrated circuit chip. Furthermore, instead of manually manufacturing an integrated circuit chip, such programming is often implemented by “logic compiler” software, which is similar to a software compiler used in program development and writing. Original code before compiling also needs to be written in a particular programming language, which is referred to as a hardware description language (HDL). There is not just one, but many types of HDLs, for example, ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, and RHDL (Ruby Hardware Description Language), among which VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog2 are the most commonly used nowadays. Those skilled in the art should also understand that a hardware circuit for implementing a logic method procedure may be easily obtained only by slightly logically programming the method procedure using the above several hardware description languages and programming the method procedure into an integrated circuit.

A controller may be implemented in any suitable manner. For example, the controller may be in the form of a microprocessor or processor and a computer-readable medium that stores computer-readable program code (for example, software or firmware) executable by the (micro)processor, logic gates, switches, an application specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. The examples of the controller include, but are not limited to the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art also know that, in addition to implementing a controller by pure computer-readable program code, with a logic programming of method or steps, the controller may implement the same function in the form of a logic gate, a switch, an application specific integrated circuit, a programmable logic controller, an embedded microcontroller, or the like. Therefore, such a controller may be regarded as a hardware component, and an apparatus included therein for implementing various functions may be regarded as an internal structure of the hardware component. Or, the apparatus for implementing various functions can even be regarded as both a software module for implementing a method and a structure in a hardware component.

The system, apparatus, module, or unit illustrated in the aforementioned embodiments may be specifically implemented by a computer chip or an entity, or a product having a certain function. A typical implementation device is a computer. Specifically, the computer may be, for example, a personal computer, a laptop computer, a cell phone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

For the sake of convenient description, the above apparatus is functionally divided into various units, which are separately described.

The present application is described with reference to flowcharts and/or block diagrams of a method, a device (system), and a computer program product according to embodiments of the present application. It should be understood that each flow and/or block in the flowcharts and/or block diagrams and a combination of the flows and/or blocks in the flowcharts and/or block diagrams may be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general-purpose computer, a special-purpose computer, an embedded processor, or any other programmable data processing device to produce a machine, such that instructions executed by the processor of the computer or other programmable data processing device generate an apparatus for implementing a specified function in one or a plurality of procedures in the flowcharts and/or one or a plurality of blocks in the block diagrams.

These computer program instructions may also be stored in a computer-readable memory that can direct a computer or any other programmable data processing device to operate in a particular manner, so that the instructions stored in the computer-readable memory produce an article of manufacture including an instruction apparatus, the instruction apparatus implementing a specified function in one or a plurality of procedures in the flowcharts and/or one or a plurality of blocks in the block diagrams.

These computer program instructions may also be loaded onto a computer or any other programmable data processing device so that a series of operational steps are performed on the computer or other programmable device to produce computer-implemented processing, and thus the instructions executed on the computer or other programmable device provide the steps for implementing a specified function in one or a plurality of procedures in the flowcharts and/or one or a plurality of blocks in the block diagrams.

In a typical configuration, the computing device includes one or a plurality of processors (CPUs), input/output interfaces, network interfaces, and memories.

The memory may include a computer-readable medium in the form of a non-permanent memory, a random access memory (RAM) and/or a non-volatile memory or the like, such as a read-only memory (ROM) or a flash memory (flash RAM). The memory is an example of a computer-readable medium.

The computer-readable medium includes permanent and non-permanent, movable and non-movable media that can achieve information storage by means of any methods or techniques. The information may be computer-readable instructions, data structures, program modules, or other data. Examples of a storage medium of a computer include, but are not limited to, a phase change memory (PRAM), a static random access memory (SRAM), a dynamic random access memory (DRAM), other types of random access memories (RAMs), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a flash memory or other memory technologies, a compact disk read-only memory (CD-ROM), a digital versatile disc (DVD) or other optical storage devices, a cassette tape, a magnetic tape/magnetic disk storage or other magnetic storage devices, or any other non-transmission medium, and can be used to store information accessible by a computing device. According to the definitions herein, the computer-readable medium does not include transitory computer-readable media (transitory media), such as a modulated data signal and a carrier wave.

It should further be noted that the term “include,” “comprise,” or any other variation thereof is intended to encompass a non-exclusive inclusion, such that a process, method, commodity, or device that includes a series of elements includes not only those elements but also other elements not explicitly listed, or elements that are inherent to such a process, method, commodity, or device. The element defined by the statement “including one . . . ,” without further limitation, does not preclude the presence of additional identical elements in the process, method, commodity, or device that includes the element.

Those skilled in the art should understand that embodiments of the present application may be provided as a method, a system, or a computer program product. Therefore, the present application may use the form of a full hardware embodiment, a full software embodiment, or an embodiment combining software and hardware. Moreover, the present application may use the form of a computer program product implemented on one or a plurality of computer-usable storage media (including, but not limited to, a magnetic disk memory, a CD-ROM, an optical memory, and so on) containing computer-usable program code therein.
